Question

If the pressure of a gas is 2.000 × 104 kPa, what is its pressure in atm?

Answer 1

Answer:

197200atm

Explanation:

There are different units to express pressure of a gas, some of them are atmosphere, Bar, Kilopascal, Pascal, torr among other.

In this exercise we need to know the equivalence between atm and Kpa.

                                             if, 1kp=0,00986atm

then,

(2,000 x104kPa)*(0,00986atm)/1Kpa= 0,00986 atm

Answer 2

Answer:

197.4 atm is the Answer.

Explanation:

Pressure can be expressed in unit of torr, mm Hg, psi, atm, kPa etc

1 atm = 760 torr = 760 mm Hg = 14.7 psi = 101.325 kPa

So Here to convert atm to kPa the conversion factor is either $\frac {1atm}{101.325kPa}$ or $\frac {101.325kPa}{1atm}$

We need the answer in atm so kPa should get cancel and it should be in the denominator

$2.000 \times 10^4 kPa\times \frac {1atm}{101.325kPa}$

=197.4 atm is the Answer.
